Review the text and flow chart completely before performing this procedure.
1 Touch the Stop button, then the Set home button to
start the Current position value shown at the bottom of
the screen at zero.
2 Small axis movements are clearly shown by chang-
ing Current position values. Touch the Test button to
start motion and observe the Current position value. It
might be necessary to touch Test twice. Be prepared to
touch the Stop button.
3 If no definite axis motion was noted, increase the
Proportional factor
by 10, touch Set home and retest
until definite axis motion is observed. Be prepared to
touch the Stop button.
4 If the Current position value moved to or near the
10 mm target position and stopped, the motor is not re-
versed.
If the Current position value continued beyond or away
from the target at increasing velocity, the motor is re-
versed and the Reverse Motor box must be checked.
5 When the motor direction setting is confirmed on
the current axis, use this procedure again to set the motor
directions of the other CNC axes. When all CNC axis
directions are configured, disconnect all motors from
power and proceed to Chapter 3: CNC Setup.
